ISA (COE15PA00026) lost board member Mónica de Greiff Restrepo on October 12, 2026, a governance change that also removed her from two board committees. El Colombiano reported the resignation and ISA's virtual extraordinary shareholder meeting scheduled for October 28, 2026.

Three events reshape the board

In March 2026, De Greiff joined the ISA board as one of its members after being nominated by Ecopetrol, according to El Colombiano.

On June 30, 2026, ISA's second-quarter results showed net income of COP 695.0 billion, up 53.00 percent from the second quarter of 2025, according to the company's results call carried by Yahoo Finance on August 3, 2026.

On October 12, 2026, De Greiff resigned with immediate effect and left the Talent Organization and Audit and Risk committees, making the October 28 meeting the next formal governance date. El Colombiano reported that the meeting will address corporate decisions.

What does the board change mean?

The immediate implication is a two-committee vacancy alongside the open board seat, while the extraordinary meeting puts ISA's governance structure on the corporate calendar. The event adds an organizational variable to a business picture defined by large regulated infrastructure commitments.

ISA's second-quarter call said investment execution reached COP 1.7 trillion, up 23.00 percent from the second quarter of 2025. The same call reported COP 28.1 trillion of investment commitments through 2030, with 85.00 percent allocated to energy transmission, 12.00 percent to roads and 3.00 percent to telecommunications.

Operating scale supports the story

For the first half of 2026, ISA reported EBITDA of COP 4.9 trillion, up 20.00 percent year over year, and net income of COP 1.7 trillion, up 9.00 percent. These figures came from the results call published by Yahoo Finance.

The investment profile also has a measurable execution angle: ISA said it was advancing 35 projects, including 32 energy transmission projects and three road projects, in the second quarter of 2026. The figures frame the board change against a capital-intensive expansion plan rather than as an isolated personnel event.

October meeting sets next marker

ISA's virtual extraordinary shareholder meeting on October 28, 2026, is the next dated corporate marker. Its timing matters because the board change affects two committees while the company is executing a COP 28.1 trillion investment commitment through 2030.

The latest reported first-half figures include COP 4.9 trillion of EBITDA and COP 1.7 trillion of net income, both periodized to the six months ended June 30, 2026. The financial scale gives the governance event a concrete operating backdrop.
